Kimber and Black were local coal miners while Jensen was a roof control specialist for the Mining Safety and Health Administration. All three men were killed when a section of the wall exploded due to a mine bounce at approximately 6:39 p.m. on Aug. 16.

Drilling efforts continue at Crandall Canyon as the fourth hole is expected to penetrate the mine cavity late Saturday. Officials have scheduled a press conference for 7 p.m., following a briefing for the families of the trapped miners.
